A study some growth characteristics for maize, Bohooth 106 variety under affecting mechanical for machine (moldboard plow type )

Abstract

The effect of the practical speed and tillage distances on maize Bohooth 106 variety and soil physical properties, under impact some mechanical properties for type tillage machine( moldboard plow ), were tested two practical speed levels of 2.409 and 3.543km.hr−1 and three levels tillage distances of 60, 65 and 70cm. The experiments were conducted in a factorial experiment under randomized complete block design with three replications. The results showed that the practical speed 2.409 km.hr−1was significantly better than the practical speed 3.543km.hr−1 as while tillage distances at range 60 cm was significantly superior to the other two levels 65 and 70 cm in all studied conditions. For practical speed 2.409 km.hr−1 and tillage distance 60cm, the fuel consumption, slippage percentage, machine efficiency, germination percentage, plant height, 1000–weight grain and the maize crop productivity, were 11.301, 10.153 L.ha−1, 10.240, 9.684%, 80.685, 82.002%, 90.803, 91.135%, 167.682, 169.163cm 223.341, 239.130 g, and 4.149, 4.258 t.ha−1. The best results have come from the overlap among the practical speed 2.409km.hr−1 and tillage distance of 60 cm, in all studied parameter.
